Despite its low water solubility, esculetin (EC) have been described to demonstrate various health benefits. Thus, we sought to develop esculetin-loaded mixed micelles (EC-M) delivery system to purposively improve biological availability and anti-hyperglycemia activity of EC. Thin-film hydration method was employed to fabricate EC-M, amid characterization with transmission electron microscopic analysis (TEM), coupled with physical properties such as particle size (PS), poly-dispersity index (PDI), zeta-potential (ZP) and stability testing. We analyzed in-vitro release and studied EC-M pharmacokinetics in rats. The hyperglycemic mice model was established with streptozotocin (STZ) to evaluate anti-hyperglycemic activity of EC-M. The PS, PDI and ZP of EC-M were 47.97 ± 0.41 nm, 0.189 ± 0.005 and -25.55 ± 0.28 mV, respectively. The release rate of EC-M increased comparable to free EC in the three media. The oral biological availability and half-life of EC-M increased respectively by 3.06 and 1.45 folds compared to free EC. Besides, we observed 46.21% decrease in blood glucose of mice in EC-M group comparable to the model control, wherein, the anti-hyperglycemic effect of EC-M was better compared to free EC. Conclusively, EC-M may ideally serve as a novel approach to enhance biological availability and increased anti-hyperglycemic activity of EC. [ABSTRACT FROM AUTHOR]
